Primary patellar dislocation injures the medial patellofemoral ligament (MPFL), the major soft-tissue stabilizer of the patella, which may lead to recurrent patellar instability. Recurrent patellar dislocation are common and may require surgical intervention. The variation in location of injury of the MPFL and the presence of an osteochondral fracture produces challenges in clinical decision ma...

Medial patellofemoral ligament (MPFL) reconstruction has a key role in patellofemoral instability surgery. Many surgical techniques have been described so far using different types of grafts (autologous, heterologous, or synthetic) and fixation techniques. The hereby described technique for MPFL reconstruction relies on the use of a biosynthetic graft (LARS Arc Sur Tille, France). Fixation is o...

A varus-producing distal femoral osteotomy (DFO) is an effective technique for the treatment of lateral patellar instability (LPI) in patients with concomitant moderate to severe valgus malalignment. Patellar maltracking and subluxation are corrected via neutralization of some of the laterally directed forces on the patella due to the valgus deformity. This can be accomplished with a distal fem...

OBJECTIVE The aim of this study was to compare the surgical results from reconstruction of the medial patellofemoral ligament (MPFL) with non-operative treatment of primary patellar dislocation. METHODS Thirty-nine patients (41 knees) with patellar dislocation were randomized into two groups. One group was treated conservatively (immobilization and physiotherapy) and other was treated surgica...

Background Patellar height has long been considered a risk factor for patellofemoral instability. However, recent pediatric literature demonstrated a reduction in patellar height measurements following medial patellofemoral ligament (MPFL) reconstruction. Purpose To assess the mean change in patellar height and the percentage of skeletally mature patients with patellar height ratios reduced t...

Abstract Background The medial patellofemoral ligament (MPFL) is always damaged after patellar dislocation. In selected patients, MPFL reconstruction necessary to restore a correct tracking. Despite the large number of different techniques reported reconstruct MPFL, there no consensus concerning optimal procedure, and debates still ongoing. present study analysed results isolated in patients wi...
